Applicaticnled April 2, 1921. Serial No. 458,003. i'

To all lwhom t may concern.: Be it known that I, JAMES H. WAGEN- Rims, of which the following is afull, clear,

and exact description, reference being had to the accompanying drawings.

This invention relates generally to automobile wheels and mio-re particularly to a novel type of rim which is intended to be applied directly to the ends of the spokes and which will receive and carry a straight side tire.

One of the objects of the invention is to provide means. to facilitate the removal of the tire from the rim without injur to| the inner tube of the-tire. Another ohject of the invention is to provide a rim of this character which can be used in connection with a detachable tire engaging ange or ring usable in connection with the tire carrying rim which is applied directly to the ends of the spokes.

With these various objects in view the invention consists in the novel features of construction hereinafter fully described yand pointed out in the appended claims.

In the drawings forming a part of this specication Fig. 1 is a transverse sectional view of a rim constructed vin accordance with my invention and having atire applied thereto; Fig. 2 isl a longitudinal sectional view of said rim; Fig. 3 is a transverse section on the line 3-3 of Fi 2; Fig. 4 is a transverse sectional view s owing a slight modification.

Referring tov the drawings A indicates the tire carr ing rim .and spokes. constituting the whee The rim is rolled from sheet metal and is in the form of an unbroken circle. In rollingthe rim I rovide the side ianges A which are shape to engage the beads of a straight side tire and the side fianges A are bent toward each other as shown at A2 to rovide a base upon which the bead seats. etween the base vportions A2the 'central portion of the rim is pressed inwardly as shown at As providinga central inwardly projecting portion of sutlicient width and depth to permit one of the beads of the shoe to be pressed down into the same at one side so as to permit the shoe at the opposite side to be lifted clear of the rim. This central inwardly projecting portion of the rim is. formed with outwardly projecting sockets A into which fits the tenon B4 formed upon the endv of the spoke. The inner tube of the tire will rest in the central inwardly projecting portion of. the rim and the internal pressure of the tire will hold.

the beads of the shoe firmly in place against the .portions A2 and A. As before stated this central' inwardly projecting portion A3 is provided to permit the be'ad of the shoe at one side to be pushed into the same after PATENT 'ol-turnal the tire hasbeen deflated. In order to rel' move the shoe 'from the opposite side of the rim and in order to provide against injury to the inner tube when a screw driver or tire tool is inserted between the rim and bead I employ form ofa'strip' of channel iron inserted in the base of the ri-m directly opposite the valve stem hole D, vsaid filler being secured at its ends to the' base of the rim as most to extend this filler about one-third of the circumference of the rim. In Fig. 4 I have a filler C preferably in the 4clearly shown at C. In practice I prefer and base portion E2 and the inwardly projecting portion E", said inwardly projecting portion having outwardly extending sockets E4 'exactly the same as previously described and thewooden s okes B will also be formed with the teno-n 4 to fit. in said sockets. The outer'side of the rim is formed with an outwardly projectingiange E5 and resting upon this ange E is the detachable iange rin E", the inner edge thereof Ff extending 1nto the central inwardly pro-(jecting portion ofthe rim'and the filler 2 is formed with an outwardly projecting vtoe iece Cs a ainst which the inwardly extendlng edge 7 of the ring E contacts. any fastening means are required to retain the detachable flange Ea'in place, they may be provided.

It is obvious tachable flange ring E the tire 'can be quickly and easily removed from the rim.

, By 4rolling the rim inthe shape herein shown and described it is obvious that I provide an exceedingly light rim and at the Incase p 10o that by-removing the.de j

same time one which will have great g lo A inner tube. This is prevented by. reason of the iiller C which supports a portion of the inner tube opposite the valve stem in substantial alinement with thev beads of the tire, so that, when a tire tool is inserted under 'the bead at these points, it willlslide under the inner tube without puncturing it.

Having thus described my invention, what I claim is:

l. A tire carrying rim adapted to receive. a tire having an inextensible bead and comprising tire retaining anges and a central i inwardly extending portion, and a filler .ar-

ranged in said inwardly projecting portion at a point removed from the valve stem hole. 2. A tire carrying rimadapted to' receive a tire having an inextensible bead and comprising an outwardly extending tire retaining flange at one side and a ring receiving flange at the opposite side and a central inwardly projecting portion, a filler arranged in said inwardly projecting portion, and a detachable tire engaging flange having its inner edge extending inwardly into the central inwardly projecting portion and engaging the filler arranged in said portion. 3. A rim having an inwardly projecting base portion and oppositely disposed bead seating portions, and means arranged Within the inwardly-projecting portion of the base to maintain a portion of the inner tube of a. tire yin substantial alignment with the bead seating portions of the rim base and whereby a tire tool can be introduced beneath the bead of said portion and an inner tube with out injury to said tube.

4., A rim having an inwardly extending base portion and bead seating portions upon opposite sides of said inwardly extending portion, and means within said inwardly extending portion for lmaintaining the contacting portion of an inner tube of a tire substantially in alignment with the bead seating portions of the rim whereby a tire tool may be introduced between that portion of the inner tube and said means without injury to the inner tube.

5, A rim having oppositely disposed seats for the beads of a tire and an inwardly projecting portion intermediate said seats and adapted to receive portions of an inner tube, said intermediate portion being provided with means for holding a portion of said inner tube substantially in alignment with f the adjacent seat portions whereby a tool may be introduced -beneath the bead and inner tube without damage to said inner tube. y

6. A tire carrying rim having oppositely disposed bead seating portions and a central inwardly projecting portion, said inwardly projecting portion being adapted to receive a portion o the inner tube of said tire, and a filler member connected to the rim within the central inwardly projecting portion, the centralY portion of said filler member being substantially in alignment with the adjacent bead seating portions of the rim.

7 A tire carrying rim having oppositely disposed bead seating portions and a central inwardly projecting portion and a ller member connected to the rim at its ends within the inwardly projecting portion, said filler member consisting of a curved plate the central portion of which is substantially in alignment with the adjacent bead seating portion ot the rim. f
